Regional planning that began in 2010 for the Kitchener-Waterloo-Cambridge-Guelph (KWCG) region was completed in April 2015 and an Integrated Regional Resource Plan (IRRP) was released.

Regional Planning Process Outcome

In addition to the implementation of provincial conservation targets and distributed generation programs, two transmission projects were identified to address near-term electricity needs in the area. The Guelph Area Transmission Refurbishment Project (GATR) has been approved and is expected to be  in-service in 2016. The development work for the switching facilities to improve reliability in the Cambridge and Kitchener areas is also underway.

These near-term actions will substantially address electricity needs in the area over the next 20 years. No longer-term needs were identified at this time.

IRRP Working Group

A Working Group consisting of the local distribution companies in the region, the local transmitter and the IESO will use the regional planning process to identify and meet local electricity needs. The Working Group consists of staff from Cambridge & North Dumfries Hydro, Guelph Hydro Electric Systems Inc., Kitchener-Wilmot Hydro, Waterloo North Hydro, Hydro One Networks Inc. and the IESO.

Area Overview

The KWCG Region is located to the west of the Greater Toronto Area in southwestern Ontario. The region includes the Region of Waterloo, the City of Guelph, Wellington County and the Township of Blandford-Blenheim (Oxford County). Under the Province's "Places to Grow" policy, the KWCG area is expected substantial continued population growth in the coming decades.

The area's electricity demand is a mix of residential, commercial and industrial loads, and includes diverse economic activities such as major educational institutions and automobile manufacturing.

Historical Context

Planning activities to address growth in this region have been underway for a number of years. In 2007, in order to meet forecast electricity demand growth in the KWCG Region, the Integrated Power System Plan (IPSP) recommended proceeding with the development of the GATR project.  As a result of the global economic recession in 2008/2009, electricity consumption declined and the development work for the GATR project was put on hold.

In 2010, a broader regional planning study of the KWCG Region was initiated. In 2012/2013, the Working Group recommended proceeding with the implementation of GATR and initiating early development work on the second 115 kV/230 kV auto-transformer at Preston TS to address imminent supply and reliability needs in the KWCG Region.  In September 2013, the GATR project was approved by the Ontario Energy Board (OEB).

In October 2013, the KWCG planning electricity supply study was transitioned to align with the OEB's new regional planning process.
